Features of the PSX-AR-AC
- Automatic Coordination of Auto Reverse and Circuit Breaker Tasks: It is both an auto reverser and a
circuit breaker. Fast, all solid state design with reliable quiet electronic reversing, no blinks, clicks or sparks!
- Adaptive Load Reset: Electronically senses if the overload is a real short or due to in-rush capacitance of sound decoders.
- Automates Reverse Loop Turnouts: Integrated stall motor or snap coil decoder, automatically lines up
switch machines when the polarity is reversed. Switch machine can also be controlled with standard DCC accessory commands or push buttons.
- Manual or Automatic Reset: Automatic reset of the breaker or a push button switch can manually reset.
- Outputs for LED Indicators: LEDs can be added to monitor input/output power and status.
- Wide Range of Current Trip Setting: Trip currents are adjusted by jumpers or CVs: 1.27 to 19.2 A
- System Reset: A single CV command sets all Addresses and CVs to original factory values.
- Output for Audio Alarm: An audible sounder can be added to the PSX-AR to alert you when there is a short.
- Booster Function for Low Current: Some boosters need help when resetting. Adding a jumper kick starts low Amp systems.
- Auto Stop with CV Reset: A photocell can detect a train in the reverse section and turn off power. A DCC command can then restore the power.
- Board size: is 5 3/4 by 3 3/4 inches, designed to fit standard Radio Shack enclosure.
Exclusive Double Reverse for the PSX-AR
We have developed and added a great new feature to the PSX-AR series. There are layouts that may have back-to-back reverse loops where auto-reversers tend to flip-flop each other at the transition from one loop to the next. As would be expected the transition is jerky or sporadic and the locomotive may just stall.
Larry Maier created a provision in the software to create a slave unit PSX-AR enabled by a CV change. The slave unit has a programmable reversing time delay so that the units reverse in sequence. This new feature is called Double Reverse Mode™.
- The new code uses CV55=0 to operate as the primary reverser (same as existing products). This is the default.
- Setting CV55=1 enables the unit as the secondary reverser. It will defer to the primary in reversing situations.
- CV65 controls the timing between the primary and secondary. Its default is 8, which seems to be fine.
Caution: The user should generally not use other values for CV65. Mis-setting it could cause the breaker to self-destruct by delaying the reverse/break action too long.
If a user has a problem, he can use CV65 to finetune things with our direction, although this generally will not be necessary.
There are (4) versions of the new PSX-AR Series Integrated DCC Circuit Breaker and Auto-Reversers:
PSX-AR DCC Solid State Auto Reverser-Circuit Breaker w/integrated (Stall Motor) Stationary Decoder. Automates Reverse Loop Turnouts.
PSX-ARFB DCC Solid State Auto Reverser-Circuit Breaker w/integrated (Stall Motor) Stationary Decoder and network Feedback. Automates Reverse Loop Turnouts.
PSX-ARSC DCC Solid State Auto Reverser-Circuit Breaker w/integrated (Snap Coil) Stationary Decoder. Automates Reverse Loop Turnouts.
PSX-ARSCFB DCC Solid State Auto Reverser-Circuit Breaker w/integrated (Snap Coil) Stationary Decoder and network Feedback. Automates Reverse Loop Turnouts.
The PSX series is a product of Larry Maier’s 20 years experience in designing and producing intelligent, solid state, DCC circuit breakers and auto reversers. The PSX specifically addresses the increased inrush current loads which occur due to large capacitors used for sound systems. This load appears as a system short circuit until the capacitors are charged. The logic in the new PSXs determines if the load is a true short or just an inrush overload.

I received my new PS-X 4-circuit circuit breaker yesterday, and installed it today in place of my existing 3-circuit circuit breaker. I purchased your new one because it was advertised as being able to handle the inrush current of sound-equipped locos, and it worked beautifully! I am using an NCE PowerHouse Pro system, and when a short-circuit occurred, I had to shut down the system using the Emergency Stop button on the ProCab. Disrupting to the operating session to say the least! My ‘acid test’ consisted of shorting out the power district containing at least three sound equipped locos, removing the short, and watching the system come on automatically. This is EXACTLY what I have wanted for a long time. Thanks again.
